Abstract Polypyrrole (PPy) has been the subject of extensive research recently as a supercapacitive material due to its high theoretical capacitance, low cost, facile synthesis, and abundance in nature. However, cyclic stability PPy alone an electrode is drawback for energy storage application. For supercapacitors (SCs), composite materials based on have developed improve their electrochemical performance. This review summarizes some recent developments field hybrid SCs. Additionally, certain recommendations are made about advancement large‒scale synthesis techniques further enhancing PPy‒based practical utility devices.

Abstract Layered double hydroxides (LDHs) are increasingly recognized as highly promising electrode materials for supercapacitors, owing to their exceptional specific capacitance, notable redox activity, and superior anion exchange capability. However, several challenges still need be addressed achieve the theoretical capacitance excellent rate capacity, including poor electronic ionic conductivity. In this study, a two‐step method was employed prepare high conducting NiCo‐LDH‐ V o materials, demonstrating enhanced electrochemical performance supercapacitor electrodes. First, NiCo‐LDH directly electrodeposited onto high‐conductivity nickel foam, which conductivity avoided effects of adhesives. Second, soak in H 2 O solution introduce more oxygen vacancies. The resulting exhibited higher electron ion diffusion ability, leading increased capacity long‐term stability (771.8 C g −1 at 1 A with an retention 92%).
